HMC675LP3ETR

Overview

The HMC675LP3ETR is a SiGe monolithic ultra-fast comparator featuring reduced swing CML output drivers and latch inputs. It supports 10 Gbps operation with a typical propagation delay of 100 ps, minimum pulse width of 60 ps, and 0.2 ps rms random jitter. The device offers an equivalent input bandwidth of 10 GHz, resistor-programmable hysteresis, and differential latch control. Power dissipation is 100 mW, housed in a 16-lead QFN package.

Feature Summary

• Features reduced swing CML output stage designed to drive 400 mV into 50 ohms terminated to ground.
• Supports high-speed latch mode or tracking comparator configuration via differential latch enable inputs.
• Includes resistor-programmable hysteresis for customizable noise immunity.
• Provides low overdrive and slew rate dispersion for consistent performance across varying signal conditions.

Applications

• Automated Test Equipment (ATE)
• High Speed Instrumentation
• Digital Receiver Systems
• Pulse Spectroscopy
• Clock & Data Restoration

Procurement Notes

Verify the specific suffix 'TR' indicates reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact pinout and thermal requirements specified in the datasheet. Cross-reference the manufacturer's discontinuance notices if applicable.

Selection Notes

Select this component for applications requiring sub-nanosecond response times and precise timing resolution. Consider the reduced swing output compatibility with downstream logic levels. Evaluate the power supply requirements against available board rails. Assess the need for latch functionality versus transparent tracking mode based on system timing constraints.

Part Context

This device belongs to the HMC675 series of high-speed comparators manufactured by Analog Devices Inc. It utilizes SiGe technology to achieve high bandwidth and low jitter characteristics. The family includes variants with different output formats such as RSPECL and RSECL versions.

Replacement Considerations

HMC675LP3E is the tape-and-reel equivalent without the TR suffix designation. HMC674LP3E is a related comparator offering PECL outputs instead of CML.
